[vpp-dev] UDP echo server-session-queue node TX event issue

Hi All, I am validating builtin echo sever client node functionality with UDP protocol by running 2 VPP instances on 2 different hosts. On VPP1, running echo server with the test command "*echo server uri udp: //1.2.3.4 / *" On VPP2, running echo client w

Re: [vpp-dev] #vpp How does VPP link DPDK lib？

Hi Wei, DPDK links(static) as part of the dpdk plugin in VPP. You can do readelf on dpdk_plugin.so Thanks Shiva On Fri, Nov 29, 2019 at 11:20 AM wrote: > We think VPP uses DPDK for data receive from nic, but it seems no dpdk lib > exist in vpp project. > we also try to use readelf to check t

Hi Liu, You missed binding of NIC devices to uio_pci_generic or vfio driver. show log confirms the same. 2019/12/31 06:01:42:932 notice dpdk DPDK drivers found no ports Thanks Shiva On Tue, 31 Dec 2019 at 19:00, gencli Liu <18600640...@163.com> wrote: > Hi everyone: > I can't ge

[vpp-dev] IPv6 UDP Datagrams with Zero Checksum- RFC complaint ?

Hi folks, I was going through ip6 code, and observed VPP skips calculating UDP checksum for packets with explicit zero checksum, and process the packet "normally". (This, after disabling HW checksum offload) But, as per RFC-2460, "*IPv6 receivers must discard UDP packets containing a zero checksu

Re: [vpp-dev] IPv6 UDP Datagrams with Zero Checksum- RFC complaint ?

Hi Ole, Thank you for your reply. I am not using any tunneling protocol in my case(IPV6+UDP+ payload) RFC 6935 says, "The update is specified for use by a tunnel protocol that transports packets that are themselves protected by a checksum." >>> In VPP we basically leave it up to the application

Re: [vpp-dev] IPv6 UDP Datagrams with Zero Checksum- RFC complaint ?

Forgot to add "reply-all", My apologies. Ole, >>> Right, so if you do not want to accept UDP zero checksum packets in your application, add the check in your code. I Agree. Just curious to know the design choice. So, by design, VPP hands over the UDP packet to "registered node" irrespective of th

Re: [vpp-dev] IPv6 UDP Datagrams with Zero Checksum- RFC complaint ?

Ole, Got it. I did go through udp local code previously and found we are doing only UDP dear port based and error handling in the node. Anyway , Thankyou so much for responding patiently. Thanks Shiva On Thu, 2 Jan 2020 at 18:11, wrote: > Hi Shiva, > > > Forgot to add "reply-all", My apolo
